Existing devices may contain partitions formatted with subpages, but the default PL35X NAND driver does not support them. This commit implements subpage read and write support for on-die ECC devices using the PL35X NAND driver. Signed-off-by: HatsyRei <yan.huan.chng@emerson.com>

This commit looks to implement 4ccba6737110, but on top of the updated pl35x-nand-controller driver. In summary, Bluefin devices contain parititons formatted with subpage support, but the default pl35x nand driver does not support reading or writing subpages. These changes enable subpage reads and writes when on-die ECC feature is enabled.
Testing: Built and deployed kernel with changes on cDAQ-9189. Observed that userspace can be reached after booting directly from NAND. Sanity-checked with mtdinfo, ubinfo at runtime.
